The 6o ro simplify and improve the construction of rear ends of the straps are secured in kerfs 27 churns, to enable a rapidv motion to be irnof spring-clamps 28, which are constructed of parted to the dasher, and to provide means suitable material, and are provided with for regulating the temperature of the cream Spring clamping-jaws 29, having bearing-reduring the operation of churning. cesses at their outer ends arranged in the in- 65 15 The invention consists in the construction ner faces and adapted t0 receive the cranks and novel combination and arrangement of of the shaft 20. These spring-clamps enable parts, hereinafter fully described, illustrated the straps to be readily disconnected from the in the accompanying drawings, and pointet cranks of the shaft 20.
